PETROLEUM-BURNER. Y

SPECIFICATION forming part of Letters Patent No. 731,170, dated June 16, 1903.

Application filed November 14. 1902. Serial No. 131,298. (No model.) v

To all whom t may concern:

Beit known that I, JOHN FRICK, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and u se'- ful Improvements in Petroleum-Burners, of which the following' is a specication.

My invention relates to improvements in petroleum-burners, and to that class in which the petroleum-oil is fed from a reservoir by gravity or by pressure to a vaporizing-tube in which the oil is converted into vapor and from which it is discharged through a nozzle into a mixing-tube and caused to commingle `with air before reaching the burner-head.

My invention consists in the novel'construction and arrangement of the burner-head and mixing-tube, in the vaporizer, and in a mechanism for regulating the flow of vapor frompump and connection shown to force the oil from the reservoir to the vaporizer. It will be understood, however, that this close relationship between the burner and the reservoir is not necessary, as the latter may be located some distance away from the burner or at a considerable height above the same to furnish the required pressure. Fig. 2 illustrates an enlarged plan view of the burner removed from the reservoir. Fig. 3 shows a longitudinal section of the burner, taken on the line 3 3 of Fig. 2. Fig. et illustrates a transverse section on the line 4. 4 of Fig. l; and Fig. 5 shows a detached section of the dischargenozzle, taken on line 5 5 of Fig.

Referring to the reference-letters of the drawings, A represents the vaporizing-tube; B, the burner-head; C, the mixing-tube, in which the vaporized oil and air are caused to commingle, and D represents the dischargenozzle arranged to regulate the flow of vapor from the mixing-tube.

The vaporizer A comprises a tube extending horizontally across the burner-head and nF' on `a stemfg.

supported in lugs b b, provided with setscrews b" b', by which the tube is detachably` voirE and provided with an oil-regulating valve A2. The opposite end of the vaporizer is provided with a'discharge-nozzle D, which is formed of two parts d and D. The part d, which may be termed the nozzle proper, is of some length and has in the end a small discharge-orice d.

The burner-head Bis made in the form of a ring, theV base portion B being hollowed out and. providedwith a cap-plate B2, and at the point of junction are a series of holes b2, which are formed by slotting the upper edges of the portion B. Extending across the ring and communicating with it at both ends is a conduit B3, which is provided with slots b3, similar to those above mentioned, and with a cover-plate B4, secured in place Yby a screw b4.' At one side of the burner-head is a curved depending portion B5, which has an opening b5 to receive the mixing-tube C.

The mixing-tube C consists of a straight -tube extending horizontally across the botgether with a screw b, holds the mixing-tube firmly to the burner-body. The slidable portion D of the nozzle is guided in a lug F, projecting out from the burner, and has on onel side a rack f, which -is operated by a pinion The slidable portion of the nozzle is also provided Within a needle D2, which is adapted to enter the orifice CZ, so that byoperating the rack and pinion the oriice may be opened and closed to any degree to regulateV the flow of vapor. The lower curved portion of the slidable tube D or its discharge end, as will be noticed, is of much greater diameter than the oriiice d', so that little or no back pressure in the tube will oecur to cause leakage at the point where one section of the nozzle telescopes lthe other. The movement of the tube D' in regulating the discharge of vapor is only slight, the movement being more particularly for the purpose of cleaning the small orifice and keeping it IOC it free from carbon deposits, so that at the two extreme positions-open `end closedthe distance traversed would not change the relative position of the end of the nozzle D and the mouth of the mixing-tube C to render the device inoperative.

Having described my invention,

formed of two telescopic tubular parts, one of which is secured to the vaporizer and provided With a valve opening and seat, and the other being siidable over the first-mentioned part and provided with a valve-needle, substantially as specified. what I l In testimony whereof I aiix my signature claim, and desire to secure by Letters Patent, l in presence of two Witnesses. isl A petroleum-burner, comprising, in combination with the burner head, vaporzer, and mixing-tube thereof, a discharge-nozzle JOHN FRICK.
